IMPROVEMENT IN WHEEL-FLOWS.

Specification forming part of Letters Patent No. 135,800, dated February11, 1873.

1 0 all whom it may concern:

Be it known that I, WILLIAM S. Gam- SHAW, of Pittsfield, Pike countyand-State of Illinois, have invented a new and useful machine foradjusting, regulating, and holding an ordinary plow of any pattern whenin use, the whole being ordinarily designated by the general name ofSulky-Plow; and I do here-. by declare that the following is a full,clear, and exact description of the construction and operation of thesame, reference being had to the annexed drawing, making a part of thisspecification.

Figure 1 is a perspective view of the whole machine. Fig. 2 is aperspective view of the stationary framefixed to the axle-tree, to whichis attached the tongue, the drivers seat, and the hand-lever, with itsaccompanying arrangements for raising the plow. Fig. 3 is a perspectiveview showing the movable frame to which the plow is attached, and thefoot-lever for lowering or depressing the plow-beam by the pressure ofthe foot.

In the following description the same letters refer to the same parts inthe different figures.

A A are the wheels running on the axle tree B. To this axle-tree isfirmly fastened the stationary frame F F. To this frame is fastened thetongue G, which also supports the driverls seat. A second and separateframe, D D, is attached tothe axle-tree by the hinges a a. In theforward end of this frame is placed the rock-shaft E, which rolls orplays in said frame. To this rock-shaft the plow-beam is fastened byordinary iron clips, and also by means of the adjustable iron rod I,bolted or otherwise fastened to the said rock-shaft E at the properdistance from the plowbeam (say, perhaps, twelve inches.) Said rod 1? isalso attached by its other end to the side or top of the plow-beam at 0,near the upright post of the plow. It passes through a staple or othersimilar device on the plow-beam, and being provided with a screw outupon it, it may be adjusted at any required length. Standing at an angleto the plow-beam this rod P serves not only as a brace or guide tosteady the plow but may be adjusted to assist in regulatingthe size ofthe furrow. The plow is drawn by hitching the team to an ordinary clevison the end of the plow-beam.

A hand-lever, H, is hinged to the frame F I, and connected by a chainwith the rocking lever 11 H, also hinged to the said frame, and thisrocking-lever is again attached by another short chain to the plow-beamover the plow. By means of this hand-lever H the the plow is raised atwill. 7

To lower or depress the plow I provide the foot-lever K hinged to theaxle-tree, and so shaped that it falls upon the cross-piece of the frameDD,while'a't the same time its forward end is convenient to the foot.When pressed upon by the foot it pushes down the frame D D containingthe rock-shaft E, to which the end of the plow-beam is fastened, thusmaking it easy to lower the plow-beam at any instant when inequalitiesof ground require it.

What I claim as my invention, and desire to secure by Letters Patent,is-

"1. The combination of the movable frame D D with the axle-tree B, saidframe having the rock-shaft E, to which the plow-beam is fastened,substantially as described.

2. The rod P attached to the rock-shaft E and the plow-beam, and actingas an adj usta ble brace and guide to the plow.

3. The foot-lever K, in its combination with the axle-tree B and theframe D D, acting as a convenient and efficient device for lowering theplow. p

4. The. combination of the movable frame D D, the rod 1?, and thefoot-lever K acting together, substantially as described, and for thepurposes herein set forth.
